Detailed Description

Provides the basic functionality for propagating a synchronization context in various synchronization models.

Constructor & Destructor Documentation

◆ SynchronizationContext()

System.Threading.SynchronizationContext.SynchronizationContext ( )

Creates a new instance of the T:System.Threading.SynchronizationContext class.

Definition at line 54 of file SynchronizationContext.cs.

Member Function Documentation

◆ CreateCopy()

virtual SynchronizationContext System.Threading.SynchronizationContext.CreateCopy ( )

virtual

When overridden in a derived class, creates a copy of the synchronization context.

Returns: A new T:System.Threading.SynchronizationContext object.

Definition at line 219 of file SynchronizationContext.cs.

◆ IsWaitNotificationRequired()

bool System.Threading.SynchronizationContext.IsWaitNotificationRequired ( )

Determines if wait notification is required.

Returns: true if wait notification is required; otherwise, false.

Definition at line 93 of file SynchronizationContext.cs.

◆ OperationCompleted()

virtual void System.Threading.SynchronizationContext.OperationCompleted ( )

virtual

When overridden in a derived class, responds to the notification that an operation has completed.

Definition at line 125 of file SynchronizationContext.cs.

◆ OperationStarted()

virtual void System.Threading.SynchronizationContext.OperationStarted ( )

virtual

When overridden in a derived class, responds to the notification that an operation has started.

Definition at line 119 of file SynchronizationContext.cs.

◆ Post()

virtual void System.Threading.SynchronizationContext.Post	(	SendOrPostCallback	d,
		object	state
	)

virtual

When overridden in a derived class, dispatches an asynchronous message to a synchronization context.

Parameters

d	The T:System.Threading.SendOrPostCallback delegate to call.
state	The object passed to the delegate.

Definition at line 112 of file SynchronizationContext.cs.

◆ Send()

virtual void System.Threading.SynchronizationContext.Send	(	SendOrPostCallback	d,
		object	state
	)

virtual

When overridden in a derived class, dispatches a synchronous message to a synchronization context.

Parameters

d	The T:System.Threading.SendOrPostCallback delegate to call.
state	The object passed to the delegate.

Exceptions

T:System.NotSupportedException The method was called in a Windows Store app. The implementation of T:System.Threading.SynchronizationContext for Windows Store apps does not support the M:System.Threading.SynchronizationContext.Send(System.Threading.SendOrPostCallback,System.Object) method.

Definition at line 103 of file SynchronizationContext.cs.

◆ SetSynchronizationContext()

static void System.Threading.SynchronizationContext.SetSynchronizationContext ( SynchronizationContext syncContext )

static

Sets the current synchronization context.

Parameters

syncContext The T:System.Threading.SynchronizationContext object to be set.

Definition at line 166 of file SynchronizationContext.cs.

◆ SetWaitNotificationRequired()

void System.Threading.SynchronizationContext.SetWaitNotificationRequired ( )

protected

Sets notification that wait notification is required and prepares the callback method so it can be called more reliably when a wait occurs.

Definition at line 60 of file SynchronizationContext.cs.

◆ Wait()

virtual int System.Threading.SynchronizationContext.Wait	(	IntPtr []	waitHandles,
		bool	waitAll,
		int	millisecondsTimeout
	)

virtual

Waits for any or all the elements in the specified array to receive a signal.

Parameters

waitHandles	An array of type T:System.IntPtr that contains the native operating system handles.
waitAll	`true` to wait for all handles; `false` to wait for any handle.
millisecondsTimeout	The number of milliseconds to wait, or F:System.Threading.Timeout.Infinite (-1) to wait indefinitely.

Returns: The array index of the object that satisfied the wait.

Exceptions

T:System.ArgumentNullException waitHandles is null.

Definition at line 140 of file SynchronizationContext.cs.

◆ WaitHelper()

static int System.Threading.SynchronizationContext.WaitHelper	(	IntPtr []	waitHandles,
		bool	waitAll,
		int	millisecondsTimeout
	)

protected

Helper function that waits for any or all the elements in the specified array to receive a signal.

Parameters

waitHandles	An array of type T:System.IntPtr that contains the native operating system handles.
waitAll	`true` to wait for all handles; `false` to wait for any handle.
millisecondsTimeout	The number of milliseconds to wait, or F:System.Threading.Timeout.Infinite (-1) to wait indefinitely.

Returns: The array index of the object that satisfied the wait.

Property Documentation

◆ Current

SynchronizationContext?? System.Threading.SynchronizationContext.Current

staticget

Gets the synchronization context for the current thread.

Returns: A T:System.Threading.SynchronizationContext object representing the current synchronization context.
